Amperage
to wire size table Here is a few charts to help you decide what size of wire you need
to run from your generator to your batteries. It is intended
to be used as a reference.
It should be close but I am not saying it is 100% accurate
How to use it:
Lets say your generator puts out 12 Amps. On the Amps line go
to the the number that is the same or larger, example: 15. Go across
the chart to the right until you get to the distance from the
batteries to the generator. Then from the distance in feet go
up to find the gauge of wire you need to use.
